KEUNE, or cARLINVILLnTLLINQIs COMBINED TRACK AND cournnve ATTACHMENT Application filed April 12,

This invention relates to a combined track and coupling attachment for doors of the slidably suspended type, and has for its ob j ect to provide, ina manner as hereinafter set forth, an attachment of the class referred to for preventing the outward swinging of the door with respect to the door frame, the warping and springing of the door, and further providing for easily shifting the latter when opening and closing it.

Further objects of the invention are to provide, in a manner as hereinafter set'forth, an

attachment of the class referred to which is simple in its construction and arrangement, strong, durable, compact, thoroughly efficient in its use, readily installed, and comparatively inexpensive to manufacture.

To the above ends essentially and-others which may hereinafter appear, the invention consists of such parts, and such combination of parts which fall within the scope of" the invention as claimed.

Y In the drawing:

Figure 4 is a section on line44-. Figure 3.

Figure 5 is'a section on line 5-5 Figure 2 with a fragmentary part. of the door end frame illustrated.

Figure 6 is a section on line 6-6 Figure 3.

Referring to the drawing, 1 and 2 indicate the sides and 3 the sillof a door frame. A slidably suspended door for opening and closing the door openin provided by the frame is indicated at 4. iecured to one side of the door frame in proximity to the sill 3, as well as projecting from the door opening is an adjustable coupling element 5. Secured to that face of the door 4 which is to oppose the door frame and in proximity to the bottom thereof is a track forming element 6 dis- 1932. Serial No. 664,815. v

The element 5 includes a holder plate 7 standing onits lower lengthwise edge and formed with an angularly disposed outer end part 8. One face of plate 7 is formed with lengthwise disposed spaced parallel ribs 9 extending from the innerend to a point re- -moved from the end part 8. The ribs are flush with the side edges of plate 7. Holdfast devices 10 are employed for fixedly securing plate 7 to the side of the door frame. The

plate 7 is also'formed with an opening 11 hav 1 ing a threaded wall.

The element 5 also includes an adjustable coupling arm 12 formed of a pair of parts 13, 1 1, the former being of greater length than the latter. The part 14 is disposed at right angles to the outer end of part; 13 and extends in an opposite direction with respect to the outer end part8 of plate 7. The part 13 is formed with a lengthwiseslot 15 for the passage of a binding screw 16 which engages with the threaded wall of'opening 11'. The slot 15 provides for the adjusting of coupling arm 12 lengthwise with respectto plate 7, and screw 16 and threaded'wall of opening 11 coact to secure arm 12 in its adjusted position. The arm 12 projects beyond the outer 'end of plate 7 and is confined between the ribs 9.

Fixedl secured by the holdfast devices 17 against t e outer face of part ll of arm 12 is a supporting element 18 formed of'ahousing 19, openat each end and having its front ill wall formed with an opening 20 to provide a .clearancefor a purpose to'be referred to. Extending through the side walls of. housing 19 and secured thereto by a holding nut 21 is a headed, threaded bolt 22 which provides a shaft for a revoluble roller 23. i p

The element 6 is secured to the door and comprises an oblong plate 24 standing on one lengthwise edge and of the desired width and length. The plate 24-is provided at each end with a stop flange 25 directed towards and abutting the door. That face of plate 24 which is to oppose the door'hasat the longitudinal median thereof a spacing rib 26 extending from one flange 25 to the other flange 25 and abutting the door. The rib 26 extends through the openings 20 in the front wall of the housing 19 and such front wall overlap the top and bottom of plate 24 when the attachment is set up relative to the door and door frame. The element 6 is secured to door 4 by holdfast devices 27 which extend through the body of plate 24, rib 26, plates 28 and engage in the body of the door. The plates 28 are countersunk in the door body. The holdfast devices 27 are countersunk in the plate 24:- The fianges coact with the housing 19 to prevent the separation of the elements 6 and 18 and also act as stops to limit the shifting movement 'of' the door in either direction. 7

The elements 5, 6 and 18 when set up couple the door with the door frame and prevent the former from swinging away from the latter, as well as preventing the warping or springing of the door and further enables the latter to be readilyshifted in the desired direction.
